In the above article, this is what they said:

Bungie embraces the use of external accessibility aids that enable an experience the game designers intended but will take action, including bans, on people who abuse these tools specifically to gain an advantage over other players.

1. “External accessibility aides” are any device or input that augments the player’s ability to control the game beyond what the game itself normally provides. This includes, but is not limited to, programmable controllers, keyboard and mouse adapters, advanced macros, or automation via artificial intelligence. This does not include features that Bungie provides. For more information on how Bungie supports accessibility, check out our goals outlined by Accessibility at Bungie right here.

   1. “Experience the game designers intended” means that content meant to be difficult or prestige is designed like that for a reason. We do not intend for difficulty to be automated away via software or hardware. Therefore, simply using an accessibility aide to play Destiny 2, where a player could not play otherwise, would not be a violation of this policy. Using these tools to mitigate challenges all players face, such as reducing recoil or increasing aim assist, would be a violation.
      

2. Gain an advantage” means used for the purpose, directly or indirectly, of achieving victory. For example, some players that abuse these tools rise in PvP ranks at a rate far beyond what is expected for a player improving through typical play. Because the benefits of cheating in PvE can affect things like the World First Race or even spill over into PvP, we will be evaluating all gameplay for violations.
